Phosphoric acid
A acid inorganic eqhelekileyo, phosphoric acid akukho lula volatilize, akukho lula ukubola, phantse akukho oxidation, nge acid commonness, i ternary buthathaka acid, acidity yayo buthathaka ngaphezu hydrochloric acid, sulfuric acid, nitric acid, kodwa yomelele ngaphezu acetic. acid, boric acid, njl. Phosphoric acid lula deliquified emoyeni, kwaye ubushushu uya kuphulukana namanzi ukufumana pyrophosphoric acid, kwaye ke ngakumbi ukulahlekelwa ngamanzi ukufumana metaphosphate.

I-Sodium Dihydrogen Phosphate
Enye yeetyuwa zesodium ye-phosphoric acid, ityuwa ye-asidi ye-inorganic, i-soluble emanzini, iphantse inganyibiliki kwi-ethanol.Isodium dihydrogen phosphate yinto ekrwada yokwenziwa kwesodium hempetaphosphate kunye nesodium pyrophosphate.Yikristale yeprismatic yeprismatic engenambala engenambala kunye noxinano oluyi-1.52g/cm².
-
I-Dibasic Sodium Phosphate
Yenye yeetyuwa zesodium ye-phosphoric acid.Yimpuphu emhlophe ethambileyo, enyibilikayo emanzini, kwaye isisombululo esinamanzi sinobuthakathaka bealkaline.I-Disodium hydrogen phosphate ilula kwimozulu emoyeni, kwiqondo lobushushu elibekwe emoyeni ukuze ilahlekelwe malunga ne-5 crystal yamanzi ukwenza i-heptahydrate, ifudunyezwe kwi-100 ℃ ukuphulukana nawo onke amanzi ekristale kwi-anhydrous, ukubola kwi-sodium pyrophosphate kwi-250 ℃.
